"It was a good visit ... had a great time," Walker said. "It's been awhile since I've been up there, and they changed the coaching staff a lot. I wanted to see all the new faces and what (they're) all about.

"They're real good. They are a work-based staff. They're trying to turn it around."

Walker, a 6-foot-4, 295-pounder, visited Memphis the previous weekend and had a visit to Kentucky in late January. None of the visits have been official visits.

On Feb. 6, Walker received an offer from Virginia Tech.

"I've got visits about every weekend (coming up)," said Walker, who said he was planning visits to Louisville (this weekend), Purdue and Arkansas.

While most schools are recruiting him as a defensive end, some are looking at moving him around the defensive line. He said Memphis also was looking at using him as a tight end.

Used mainly as a blocking tight end for Smyrna, Walker caught four passes for 54 yards and a touchdown last season.

He said he planned to take the next several months to ponder his future but hopes to make a decision before his senior season. "Not too early, but hopefully a couple of weeks (before the season), where I will know what I have going into the season."

Walker hasn't been the only area 2020 recruit busy lately.
